Release

Evidence packs and explicit runtime provenance

InvarLock 0.8.0 moves the public bundle surface to evidence packs, pins docs to versioned release paths, and makes container-vs-host runtime provenance explicit across evaluate and verify.

Research Note

Fail-Closed Verification for Weight-Edit Evaluation

A verifier is only useful if it rejects incomplete evidence. InvarLock's verification path is designed to stop stronger claims when the evidence bundle is missing or inconsistent.

Release

Tag-based publishing with slimmer release verification

InvarLock 0.7.2 simplifies the public release surface around immutable source tags plus the PyPI wheel and sdist, with docs and verification gates aligned around that path.

Research Note

Why Paired Evaluation Beats Before/After Benchmarks

A model-edit benchmark number is only as strong as the comparison behind it. Pairing makes the comparison inspectable.

Release

Standalone contract bundles with tighter release gates

InvarLock 0.7.1 makes wheel-only verify/report workflows first-class, ships a public contract bundle, and tightens supply-chain and release-validation gates.

Release

GPT-OSS pilots with CUDA-ready attested lanes

InvarLock 0.7.0 adds first-class GPT-OSS support, pilot Ministral 3 8B/14B presets, and a CUDA-capable attested runtime path for GPU hosts.

Research Note

What InvarLock Actually Claims

A narrow claim can be stronger than a broad one. InvarLock is about auditable regression risk from weight edits, not general model safety.

Gemma 4 pilot lanes with a clearer assurance contract

InvarLock 0.6.0 adds a shipped Gemma 4 E2B text lane, phase-1 multimodal evaluation, and a unified `--assurance attested|trusted-local` workflow.

Release

Offline release verification with a slimmer public CLI

InvarLock 0.5.0 adds offline release-verification bundles, package-native proof-pack verification, and a simplified public CLI centered on evaluate, verify, and report.

Release

Stable public contracts with stricter fail-closed verification

InvarLock 0.4.0 stabilizes contracts around policies, proof packs, and evaluation provenance while tightening verification, CI, and coverage enforcement.

Release

Coverage floors and fail-closed CLI/reporting paths

Split-module coverage thresholds now protect critical CLI/reporting paths while config, plugin, report, overhead, and observability edge cases fail closed more reliably.

Release

Quantization, spectral, and report-schema hardening

A focused hardening release: safer AWQ plugin discovery, stronger quantization clipping behavior, and broader report-schema acceptance for edge payloads.

Release

Proof-pack showcase coverage and reproducible CI

Proof packs add new showcase and evidence artifacts, while CI and release flows become more deterministic and easier to validate repeatedly.

Release

Report rename cleanup and offline proof-pack hardening

A stability-focused release: cleaner report output, safer offline proof-pack flows, and CI/test hardening after the report rename.

Release

Proof packs v2 and role-based adapter routing

Adapters move to role-based routing, proof packs become easier to inspect (v2 layout), and reporting output gets a readability upgrade.

Release

Measurement contracts for CI and release verification

Reports now record and enforce estimator measurement contracts under CI/release profiles, and proof pack suites can cleanly split calibration vs execution.

Release

Deterministic proof packs and safer perplexity runs

Proof packs gain a deterministic bash test suite and better runtime helpers, window selection becomes stable/offline, and perplexity runs get safer around bad token IDs.

Release

Fail-closed baseline pairing with lower-memory retries

CI/release baseline pairing is fail-closed (pairing evidence is required), and adapters reduce peak memory during retries via chunked snapshot/restore.

Release

Token-weighted paired statistics and stricter release gates

Token-weighted paired bootstrap lands across the pipeline, strictness toggles expand, and CI/release pairing expectations become explicit and enforceable.
